BACKGROUND OF THE INVENTION

Glycopeptide antibiotics, which have a complex polycyclic peptide structure, are produced in various microorganism and effective to most gram-positive bacteria as an antimicrobial. In recent years, there are emergences of drug-resistant strains such as penicillin-resistant, cephalosporin-resistant, and serious problems of infections with multidrug resistant and methicillin-resistant Staphylococcus aureus (MRSA) has been raised in clinical practice. Glycopeptide antibiotics, such as vancomycin, are effective typically to these resistant strains, and vancomycin has been a drug as an ultimate tool for infections with MRSA and other resistant strains.

In certain strains, however, there is growing concern of emergence of resistance to vancomycin, such as vancomycin-resistant enterococci (VRE). VRE has a different mechanism and degree of resistance, depending on the gene type of a resistance-related gene such as Van A, B, C, D, E, G. For example, teicoplanin, which is a glycopeptide antibiotic as with vancomycin, is effective to Van B type VRE. On the other hand, effective glycopeptide antibiotic has not been released for Van A type VRE, while clinical measures to fight such resistant strain is especially needed. Furthermore, Staphylococcus aureus that has acquired the resistance of VRE (VRSA) has been discovered recently. Therefore, need for development of glycopeptide derivative having improved activity and/or selectivity exists. Many vancomycins and other glycopeptide derivatives have been known in the art. See, e.g., references as follows.

(2) General Procedure

Below is described a representative procedure for the production of a compound of the invention. The preparation of the compound is not intend to limit to such procedure, and of course, can be conducted by another procedure.

The compound of the invention may be synthesized using vancomycin or its known derivative as a starting material, by chemical modification of the amino moiety (R^(A)) at the amino sugar, or the C terminal (R^(B)), the resorcinol moiety (R^(C)), or the methylamino moiety at the N terminal (R^(D)). Such chemical modification can be conducted according to the procedure, for example, as disclosed in Japanese Patent Publication No. 7-258289, WO00/39156, Japanese Patent Publication No. 2001-163898. Specifically, it may be conducted in the following manner.

1) Modification of R^(A) Moiety

-   -   Typically, vancomycin as a starting material may be reacted,         optionally in the presence of a base, with a different aldehyde         corresponding to R^(A) moiety of the formula:         —X¹—Ar¹—X²—Y—X³—Ar²         to form an intermediate Schiff base, followed by reduction to         N-alkylate to afford a desired secondary amine.

Specifically, the Schiff base formation is conducted in a polar solvent such as dimethylformamide or methanol or mixture thereof, optionally under inert atmosphere such as nitrogen or argon gas and optionally in the presence of a base, at a temperature between about 25° C. and about 100° C. Preferably, the reaction is conducted at room temperature to 100° C., preferably about 60° C. to about 80° C., for about 30 minute to 2 hours. The base used in the reaction is, for example, alkylamine (e.g., diisopropylethylamine, etc).

The intermediate Schiff base, preferably without purification, may be reduced with a hydrogenated metal complex or subjected to a catalytic reduction. For such hydrogenated metal complex, a metal borohydride, such as sodium borohydride or sodium cyanoborohydride, may be used. The catalytic reduction may be conducted using hydrogen in the presence of homogeneous or heterogeneous catalysis such as Crabtree catalyst, Wilkinson catalyst, palladium on carbon, platinum on carbon or rhodium on carbon. The reduction reaction is conducted at about 25° C. to about 100° C. for about 1 to 24 hours. Preferably, the reaction is conducted in the above solvent, using an excessive amount (e.g., 3-5 equiv) of sodium cyanoborohydride at about 60° C. to about 80° C.

2) Modification of R^(B) Moiety

Typically, the carboxylic acid moiety at the C terminal of the vancomycin skeleton may be amidated using an appropriate reagent according to a conventional procedure to provide a different amido derivative wherein R^(B)=—NHNR^(X)R^(Y) or —NR^(Z)OR^(W).

When R^(B) is a group of the formula —NHNR^(X)R^(Y), a compound of the formula NH₂NR^(X)R^(Y) (wherein R^(X) and R^(Y) are as defined above) can be used to react in an appropriate solvent (dimethylformamide (DMF) etc.) with the carboxyl group at the C terminal of the vancomycin skeleton, in the presence of benztriazole-1-yl-oxy-tris-(pyrrolidino)phosphonium hexafluorophosphate (PyBOP), diisopropyl ethyl amine (DIPEA), etc.

When R^(B) is a group of the formula —NR^(Z)OR^(W), a compound of the formula NHR^(Z)OR^(V) (wherein R^(Z) is as defined above and R^(V) is a hydroxy protecting group or R^(W) as defined above) can be used to react in an appropriate solvent (dimethylformamide (DMF) etc.) with a carboxyl group at the C terminal of the vancomycin skeleton, in the presence of benztriazole-1-yl-oxy-tris-(pyrrolidino)phosphonium hexafluorophosphate (PyBOP), diisopropyl ethyl amine (DIPEA), etc.

The reagents used in the above reactions are commercially available or can be prepared readily according to procedures well known in the art using reagents as commercially available.

The amindation can be conducted preferably in a solvent such as dimethylformamide, etc. at room temperature or under heating for several minutes to several hours.

3) Modification of R^(C) Moiety

Typically, vancomycin as a starting material may be subjected to alkylation of the resorcinol moiety, according to a conventional procedure.

4) Modification of R^(D) Moiety

Typically, vancomycin as a starting material may be subjected to N-alkylation of the methylamine moiety at the N-terminal, according to a conventional procedure.

(Step 1)

Under nitrogen gas stream, 50 g of 2-piperidine-4-ylethanol (r) (0.387 mol) was dissolved in tetrahydrofuran (1 L), and after ice cooling, 78.6 g of 1-isocyanate-4-trifluoromethoxy-benzene (0.387 mol) was added dropwise to keep the mixture at the temperature bellow 10° C. and then stirred at this temperature for 1 hour. The mixture was concentrated in vacuo to achieve ⅓ of the total volume. The residue was added with diisopropyl ether and stirred for 5 minutes, and then filtered to collect the precipitate, which was rinsed with diisopropyl ether and dried to afford 120.1 g of the titled compound (4-(2-hydroxyethyl)-piperazine-1-carboxylic acid (4-trifluoromethoxyphenyl) amide: s) as colorless crystal (yield 93%).

(Step 2)

4-(2-hydroxyethyl)-piperazine-1-carboxylic acid (4-trifluoromethoxyphenyl)-amide (s) (8.0 g, 24.1 mmol) was suspended in dichloromethane (80 mL). After ice cooling, 8.38 mL of diisopropylethylamine (48.1 mmol) and 10.1 mL of dimethylsulfoxide (72.3 mmol) were added sequentially. Sulfur trioxidepyridine complex (7.66 g, 48.1 mmol) was then added portionwise to keep the temperature bellow 10° C., and the mixture was stirred for 10 minutes. Water (80 mL) was added to quench the reaction, and the mixture was extracted with ethyl acetate. The extract layer was washed sequentially with saturated sodium bicarbonate and saturated saline, and dried on anhydrous magnesium sulfate. The desiccant was removed by filtration, and the filtrate was concentrated in vacuo to afford 10.6 g of the titled compound (4-(2-oxo-ethyl)-piperidin-1-carboxylic acid (4-trifluoromethoxy-phenyl)amide: t) as yellow crude solid. Titer was 0.65, and the yield was 87%, as confirmed by ¹H-NMR spectroscopic analysis.

(Step 3)

Vancomycin hydrochloride (20.8 g, 14 mmol) and 4-(2-oxoethyl)-piperidin-1-carboxylic acid (4-trifluoromethoxyphenyl)amide (t) (6.94 g, 21 mmol) prepared in Step 2 were dissolved in dimethylformamide (208 mL), and diisopropylethylamine (9.37 mL) was added to the mixture and stirred at room temperature for 75 minutes. To the mixture, trifluoroacetic acid (4.3 mL) was added slowly dropwise over 10 minutes. The mixture was then added with methanol (208 mL) and further sodium cyanoborohydride (1.76 g) and stirred at room temperature for 3 hours. Methanol was removed in vacuo, and the residue was poured into 2.0 L of ethyl acetate. The precipitate was collected by filtration, and the obtained crude solid was rinsed with 10% saline to remove sodium cyanoborohydride. The crude solid was purified by reverse phase column chromatography to afford 10.19 g of the titled compound (u) (yield 41%).

(Step 4)

The compound (u) as prepared in Step 3 (485 mg, 0.275 mmol), benztriazole-1-yl-oxy-tris-(pyrrolidino)phosphonium hexafluorophosphate (200 mg, 0.385 mmol) and benztriazole-1-ol (38 mg, 0.289 mmol) were dissolved in dimethylformamide (8 mL), and the mixture was stirred at room temperature for 1.5 hours. Diisopropyl ethylamine (0.24 mL) and o-(tetrahydro-2H-pyran-2-yl)hydroxylamine (64 mg, 0.55 mmol) were added sequentially at room temperature, and the mixture was stirred at this temperature for 1.5 hours. The mixture was poured into 60 mL of diethylether, and the precipitate was collected by filtration. The crude solid thus obtained was dissolved in a mixed solvent of acetonitrile (8 mL) and 0.5N hydrochloric acid (6 mL), and the mixture was stirred at room temperature for 1.5 hours. The mixture was subjected to purification by reverse phase column chromatography to afford 202 mg of the titled compound (Compound 4) as colorless solid (yield 41%).
